Receiver Optical Characteristics
(TC = 0 °C to +80 °C, VCC = 3.3 V ± 5%, Typical TC = +40 °C, VCC = 3.3 V)
Notes:
1. Sensitivity is defined as the OMA necessary to produce a BER of 10-12 at the center of the Baud interval using a 2.5 GBd Pseudo Random
Bit Sequence of length 27 – 1 (PRBS), or equivalent, test pattern. For this parameter, input power is equivalent to that provided by an ideal
source, i.e., a source with RIN and switching attributes that do not degrade the sensitivity measurement. All channels not under test are oper-
ating receiving data with an average input power up to 6 dB above PIN MIN.
2. Saturation is defined as the OMA that produces at the center of the output swing a receiver output eye width less than 120 ps where BER <
10-12 using a 2.5 GBd Pseudo Random Bit Sequence of length 27 –1 (PRBS), or equivalent, test pattern.
3. Stressed receiver sensitivity is defined as the average input power necessary to produce a BER < 10-12 at the center of the Baud interval using
a 2.5 GBd Pseudo Random Bit Sequence of length 27 – 1 (PRBS), or equivalent, test pattern. For this parameter, input power is conditioned
with 2.5 dB Inter-Symbol Interference, ISI, (min), 120 ps Total Jitter, TJ (min). All channels not under test are operating receiving data with an
average input power up to 6 dB above PIN MIN.
4. Stressed receiver eye opening is defined as the receiver output eye width where BER < 10-12 at the center of the output swing using a 2.5 GBd
Pseudo Random Bit Sequence of length 27 – 1 (PRBS), or equivalent, test pattern. For this parameter, input power is an average input optical
power of –10.4 dBm and conditioned with 1.2 dB ISI (min), 120 ps TJ (min), All channels not under test are operating receiving data with an
average input power up to 6 dB above PIN MIN.
5. Return loss is defined as the ratio, in dB, of the received optical power to the optical power reflected back down the fiber.
6. Signal Detect assertion requires all optical inputs to exhibit a minimum -15 dBm OMA. All channels not under test are operating with PRBS 7
serial encoded patterns, asynchronous with the channel under test, and an average input power up to 6 dB higher than PIN MIN.
